 In a physical classroom, there are three basic elements, the learner, the content and the teacher. The teacher utilizes various strategies and available tools to facilitate effective teaching learning interactions between these elements. So while moving from this physical setting to online learning like the one in IIT Bombay X, the three main elements still remain the same. So you can play the video or pause it by clicking on the play or pause button. So you can play the video or pause it by clicking on the play or pause button. On top of this you see the seek bar through which you can move to any portion of this video either forward or backward.

The learner content interaction can happen through both LEDs and LBDs. Similarly, learner facilitator interaction can happen through both LED and LXIs. Only the learner-learner interaction will have a direct match with LXIs. The learner content interaction can happen through both LEDs and LBDs. Similarly, learner facilitator interaction can happen through both LED and LXI's. Only the learner-learner interaction will have a direct match with LXI's.
